Startup Pitaka knows the frustration of accidentally forgetting your phone or wallet at home. Its MagHive sensors, available starting in early 2018, are supposed to keep you from leaving home without your stuff.

Pitaka's MagHive kit includes a base station and sensor fobs called MagTags. Once your keys, phone and other things are paired to MagHive, motion, local weather conditions and more can create an alert to make sure you don't head outside without your umbrella and other things that might come in handy.

So, unlike Tile, Trackr and other locating tech, MagHive should, in theory, keep track of your things and also not let you leave home without them. MagHive will also be compatible with Amazon's Alexa and Google Assistant.

I have a lingering question, though -- if the alerts are delivered through your phone (and you've forgotten your phone) you won't know to grab your umbrella, keys or other forgotten items. We'll just have to see the devices in action to confirm how they work -- and to learn if it's necessary to mount an Amazon Echo Dot to the wall for its voice integrations to work (see picture above).
